Default i need a jig that will cut a concave curve on a thick board

i want to make a low bench 8" wide, 18" long, about 3-4" thich with a curved concave top, sorta Asian style.

i saw an old fuzzy photo from an old book, of a jig that did that, on line, but i lost it.!!

it had a base guide each side of the curve desired, looked like the router was on a little sled with arms that rode on the base.. back and forth, moved side to side over the board to route it down.. it wasn't clear at all. i dont know enough about routers to figure out how to do that safely.

has anyone ever seen something like that.? got a link>> ??

Try searching this forum for "router skis". That sounds like what you were looking at.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Default A vertical bandsaw cut on your board would do 95% of the work

Hi NL,

A single vertical bandsaw cut on a 2-inch by 8-inch by 18-inch board would do 95% of the work of making the top. If your bandsaw cannot handle 8 inches, then you could cut and glue up two 4 inch boards. Your router can then finesse the edges.

Think of the pit and the pendulum,you don't need a DVD to make a simple jig to hold the router for you.
Or

If you have a RAS it will do the job fine or you can mount a router to the RAS..

I know that this is late, Take a look at Woodsmithshop.com or in the book It is what You are looking for. Fairly easy to make, I think!

$19.00 for that 2 3/4" Crown moulding bit is a bargain Bob.

Hi Harry, I have used it to make half a dozen small benches out of hoop pine (450mm high x 600mm long 450 mm wide) with a foldable tray for a friend, he uses them in the barbeque's area rather than plastic chairs, also 2 garden benches 1200mm long that also gets utilized at his barbeque's.

Regards
Harold
